Current Concepts in Epidemiology, Diagnosis, Associated Co-Morbidities, and Therapeutics of Non-Melanoma Skin Cancers: Beyond Basal Cell and Squamous Cell Carcinomas

Non-melanoma skin cancers are a heterogeneous group of cutaneous malignancies. Often this term is used synonymously with basal and squamous cell carcinomas. They are by far the most frequently seen in this group and therefore the most "visible". However, morbidity and mortality from the other less frequently seen malignancies can be quite high. Thus, they deserve more "visibility", thereby helping clinicians have a lower index of suspicion for their diagnosis.

This Research Topic aims to provide space for discussion and debate on other less frequently encountered cutaneous neoplasms, which are often not widely discussed, in order to provide a source of current data for researchers in this very diverse field. We look forward to showcasing current concepts in epidemiology, diagnostics, and therapeutics of this large group of uncommonly encountered malignancies. Associated co-morbidities may also be discussed. This current data collection will provide clinicians and other healthcare workers with the most recent data to help them recognize and care for these less-frequently seen malignancies.

This Research Topic will cover the epidemiology, clinical and pathological (microscopy, immunohistochemistry, etc.) aspects of the less commonly seen non-melanoma cutaneous malignancies ranging from Kaposi's sarcoma to dermatofibrosarcoma protuberans, and metastatic skin tumors. Our keywords serve as a guide, but they are not to be considered exclusive of disorders not listed therein. We are open to those not mentioned explicitly in that list of conditions. Original research articles, review articles, systematic reviews, and clinical trials are welcome in this collection. In addition, the rarity of some of these conditions means that case reports will constitute important accepted manuscripts.
